HU research team achieves breakthrough in battery technology
A research team at Humboldt-Universität zu Berlin has achieved a decisive breakthrough in battery technology. The team, led by IRIS Adlershof member Prof. Dr. Michael J. Bojdys, has developed an innovative sulphur-based cathode that enables the use of more environmentally friendly and sustainable materials in lithium-ion batteries. The results of this groundbreaking study were published in the renowned journal Angewandte Chemie on April 15, 2024.
Challenges of current battery technology
The new technology, which encapsulates sulfur in a special microporous imine polymer network, not only demonstrates increased battery performance and durability, but also addresses the critical problem of resource scarcity in conventional battery materials.
"This development could fundamentally change the way we store and use energy and represents an important step towards a more sustainable future," explained Prof. Bojdys. The microporous network encapsulates the sulfur, reducing polysulphide diffusion, a significant issue with sulfur cathodes. This results in a more stable and longer-lasting battery.
Importance for the region and global impact
Prof. Dr. Michael J. Bojdys is a leading expert in the field of sustainable energy materials. He is spearheading the transformation of the chemical industry in the Berlin capital region into a circular economy based on sustainable raw materials by linking science and industry as part of the BMBF's "GreenCHEM" initiative.
The battery industry in the Berlin-Brandenburg Airport Region has experienced a significant increase in activity in recent years, with numerous companies from the entire battery technology value chain establishing a presence in the region. This has led to a notable economic revival. The development offers not only local benefits but also global advantages, as it reduces dependence on rare and expensive materials and provides more environmentally friendly alternatives.
Research and innovation are key drivers of success in the battery industry in Berlin-Brandenburg. A study commissioned by the Brandenburg Economic Development Corporation (WFBB) identified approximately 130 players in the region, including 86 companies and 29 research institutions. These players are not only networked locally, but also internationally, which enables and promotes cross-border innovation cooperation.
Significance for the regional economy
The battery industry has developed into a central element of modern industry in the region. Brandenburg's Minister for Economic Affairs, Labor and Energy, Prof. Dr.-Ing. Jörg Steinbach, highlights the significance of this industry for the economic development and transformation of the state of Brandenburg. The dynamic development of the battery industry presents a valuable opportunity for the creation of new jobs and the promotion of innovation.
